Abstract

PCT No. PCT/EP97/03885 Sec. 371 Date Nov. 15, 1999 Sec. 102(e) Date Nov. 15, 1999 PCT Filed Jul. 19, 1997 PCT Pub. No. WO98/08583 PCT Pub. Date Mar. 5, 1998A process is disclosed for separating a component from a gaseous mixture, in particular for separating xenon from the breathing gas exhaled by an anaesthetized patient. The disclosed process has the following steps: the gaseous mixture is brought into contact with a cooling surface at a temperature below the melting point of the components to be separated, the proportion of the gaseous mixture which is not condensed on the cooling surface in a solid state is carried away, and the component condensed on the cooling surface is heated above the melting point of the component to be separated. Also disclosed are a device for carrying out this process, a corresponding process for recovering anaesthetic gas and an associated anaesthetic equipment.
